BATTERY MANAGEMENT SYSTEM
First Claim
1. A method, implemented by a controller of a battery management system in a healthcare delivery system, of managing one or more batteries in the healthcare delivery system when the healthcare delivery system is not drawing power from a power supply other than the one or more batteries, the method comprising:
- determining when the healthcare delivery system is drawing power from the one or more batteries;
controlling a display unit coupled to the controller to display an initial number corresponding to a time remaining on battery (TROB) when the healthcare delivery system is drawing power from the one or more batteries;
determining if the TROB is within a reserve range extending up to a reserve range maximum, the reserve range maximum being less than a maximum TROB;
changing the TROB according to an operational state of the healthcare delivery system if the TROB is greater than the reserve range maximum; and
decreasing the TROB to count down the TROB without regard for the operational state of the healthcare delivery system if the TROB is less than the reserve range maximum.

Abstract
A battery management method for one or more batteries in a healthcare delivery system is provided. The method includes determining when the healthcare delivery system is drawing power from the one or more batteries and controlling a display unit coupled to the controller to display an initial number corresponding to a time remaining on battery (TROB) when the healthcare delivery system is drawing power from the one or more batteries. The method also includes determining if the TROB is within a reserve range extending up to a reserve range maximum that is less than a maximum TROB, changing the TROB according to an operational state of the healthcare delivery system if the TROB is greater than the reserve range maximum, and decreasing the TROB to count down the TROB without regard for the operational state of the healthcare delivery system if the TROB is less than the reserve range maximum.

11. A method, implemented by a controller of a battery management system in a portable pump for use in intravenous delivery of medical fluids, of managing one or more batteries in the portable pump when the portable pump is not drawing power from a power supply other than the one or more batteries, the portable pump including (i) a display unit, (ii) an input unit, (iii) a pump controller coupled to the portable pump, the display unit, and the input unit and programmed to receive an input from the input unit and to control the portable pump to enter an operational state according to the input received, and (iv) and a battery management system comprising a charger coupled to the one or more batteries and a controller coupled to the display unit and operable to implement the method, the method comprising:
-
determining when the portable pump is drawing power from the one or more batteries; controlling the display unit to display an initial number corresponding to a TROB when the portable pump is drawing power from the one or more batteries; determining if the TROB is within a reserve range extending up to a reserve range maximum, the reserve range maximum being less than a maximum TROB; changing the TROB according to an operational state of the portable pump if the TROB is greater than the reserve range maximum; decreasing the TROB to count down the TROB without regard for the operational state of the portable pump if the TROB is less than the reserve range maximum; activating the charger when the portable pump is drawing power from the mains voltage to charge the one or more batteries; and increasing the TROB either by a first increment or to the TROB maximum according to a recharge state of the one or more batteries. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
